(3) DV bias voltage adjustment
1
Set the digital multi meter range to DCV 300V or greater.
2
Put test rods to the DV bias output check pin (BSCP) of the high
voltage unit and the chassis (GND).
3
Execute simulation 8-1. (A DV bias voltage is outputted for 30
sec.)
4
Adjust the DV bias voltage adjustment volume (VR-301) so that
the output voltage is –200V
±
5V.
(4) Note for installation of rollers to the developing
unit
1
Be careful to the installing direction of the V ring.
2
Allow no clearance between the V ring and the rollers (sections
marked with "
*
").
3
Installation of

8V ring,
φ
8 C ring, and
φ
5V ring.
Developing magnet roller
1) Be careful to the V ring direction as shown in the figure above.
2) Allow no clearance between the V ring and the rollers (sections
marked with "
*
").
(5) Note for developing side seals F/R attachment
1
Attach developing side seal F so that the slit is aligned with line E
and the edge with the line D.
2
Attach developing side seal R so that the slit is aligned with line C
and the edge with line D.
